Garry decided to raffle 'Banjo' the brumby to raise money for the McGrath Foundation, the breast cancer charity that supported his wife when she was ill.

"I needed something to do and I came up with this idea of giving something back to them," Garry told ABC Goulburn Murray's Bronwen O'Shea.

He spent four months taming 'Banjo' the brumby and said it gave him a new focus after the loss of his wife.

"Every time I work with him I think of my wife. She just loved brumbies. If I can make it easier for just one person it's all worthwhile, if it just helps one family. You can make a difference if you try."
